Very partial code for parsing out campl.us urls and finding source image url

campl.us_partial.rb

require 'net/http'

# in the main tweet parser. tweet_text is the status.text string
# match short campl.us urls:
if tweet_text =~ /\((http:\/\/campl.us\/\w+?)\)/
	picurl = $1
	# grab the source and parse out the full size image url
	final_url = get_body(picurl).match(/"(http:\/\/pics.campl.us\/f\/c\/.+?)"/)
	return false if final_url.nil?

	# do what you want with it...
end

# function to pull the source page of the url
def get_body(sourceurl)
	url = URI.parse(sourceurl)

	host, port = url.host, url.port if url.host && url.port
	req = Net::HTTP::Get.new(url.path)
	res = Net::HTTP.start(host, port) {|http| http.request(req) }
	return res.body
end
